Fig. 6. Expression of myofilin RNA and protein in the Drosophila embryo. (A) Stage 15-17 embryo hybridised with a digoxigenin-labelled myofilin RNA probe. (B) Higher magnification of the same embryo showing labelling of somatic muscles, but not heart or visceral muscles. (C) Stage 15-17 embryo labelled with anti-myofilin antiserum, showing specific immunostaining of somatic muscles. (D) Higher magnification of the same embryo. Labelling of individual muscles can be clearly seen at this embryonic stage. Embryos are seen in lateral view with anterior to the left.
